Nightly repositories
To benefit from the best experience of our nightlies, you should use our repositories. They are available for Debian (and similar distributions like Ubuntu) and RedHat distributions (esp. Centos and Fedora). Using an Odoo nightly repository, you will be able to install and upgrade Odoo with the help of your traditional package manager (apt or yum).
If you plan to run the PostgreSQL cluster on the same host than the Odoo one, install PostgreSQL before. This way, Odoo will be able to create and configure its user.
If you want to use a nightly repository for the 7.0 version, the name of the package is openerp.
Setup of the Debian nightly repository details
wget -O - https://nightly.odoo.com/odoo.key | apt-key add -
echo "deb http://nightly.odoo.com/8.0/nightly/deb/ ./" >> /etc/apt/sources.list
apt-get update && apt-get install odoo
Setup of the RedHat nightly repository details
yum-config-manager --add-repo=https://nightly.odoo.com/8.0/nightly/rpm/odoo.repo
yum update && yum install odoo
if Do that why to install odoo then default path of the odoo is
addons_path = /usr/lib/python2.7/dist-packages/openerp/addons
and you clone into the github so run your like that
openerp: addons paths: [u'/home/xyz/odoo/master-test/openerp/addons', u'/home/xyz/odoo/master-test/addons']
so no need to uninstall odoo and keep run the ODOO.
Thank you may be this is help full you.
